Schema and Links Governance

Protect ontology consistency during schema and validator changes.

Required Workflow

1. •If changing schema fields, update all dependent files:
   • •schema/equation-node.schema.json
   • •data/statistics/nodes.json
   • •scripts/validate_nodes.py
2. •Keep inferential_links contract intact:
   • •entailed_by
   • •entails
   • •equivalent_to
   • •special_case_of
   • •generalizes
   • •composed_with
3. •Enforce reciprocity:
   • •entails <-> entailed_by
   • •generalizes <-> special_case_of
   • •equivalent_to symmetric
4. •Run python scripts/validate_nodes.py.

Change Discipline

• •Prefer additive schema evolution where possible.
• •Avoid implicit renames.
• •Keep field names academically precise.
